Abstract: The objective that lasted 270 days was to evaluate the production, chemical composition, somatic cell count in milk and body condition score in Ayrshire cows. About 20, first lactation cows were randomly assigned to one of two treatments: T1 = control, T2 = selenium and vitamin E. Identical management and diets were fed in both treatments. Performance responses to Selenium (Se) and vitamin E supplementation increases (p<0.05) daily Milk Production (MP) T1 = 8.63 vs. T2 = 9.34, percentage of Crude Protein (CP), Solids Non Fat (SNF) and lactose. Percentage of Milk Fat (MF) and content of Total Solids (TS) was not affected by treatment (p>0.05). Decreased number (p<0.05) of Somatic Cells Count (SCC) was attributable to dietary Se and vitamin E supplementation (2.053 vs. 1.509). Body Condition Score (BCS) in both treatments was similar between treatments (2.5-3.0). Researchers conclude that the incorporation of Se and vitamin E in commercial diets of grazing first lactation cows increases MP and percentage of CP, SNF and lactose content and decreases SCC while BCS of animals were unaffected by treatment. This data confirm earlier findings that Se and vitamin E supplementation are related to mammary health gland. The performance and economic feasibility of the use of selenium plus Vit. E allowed us to obtain a profit margin of $0.21 (US cents) per animal per day in this study.
